A Creative Cartoonist Rube Goldberg, 1923, Popular Science Magazine • Pulitzer Prize winning cartoonist, sculptor, and author • Went to college to become an engineer • moved from San Francisco to New York drawing daily cartoons for the Evening Mail • believed that there were two ways to do things: the simple way and the hard way • Through his cartoon inventions, Goldberg discovered difficult ways to achieve easy results • To see some of Rube Goldberg’s original cartoon inventions, visit this webpage: • Rube Goldberg Cartoon Gallery • Videos of students’ Rube Goldberg machines can be found at 8th grade Rube project or Katie's 6th grade project • Or here amazing Rube machine • 1. Turn the handle on a toy cash register to open the drawer.2. The drawer pushes a golf ball off a platform, into a small blue funnel, and down a ramp.3. The falling golf ball pulls a string that releases the magic school bus (carrying a picture of Rube Goldberg) down a large blue ramp.4. Rube's bus hits a rubber ball on a platform, dropping the ball into a large red funnel.5. The ball lands on a mousetrap (on the orange box) and sets it off.6. The mousetrap pulls a nail from the yellow stick.7. The nail allows a weight to drop.8. The weight pulls a cardboard "cork" from an orange tube.9. This drops a ball into a cup. 10. The cup tilts a metal scale and raises a wire.11. The wire releases a ball down a red ramp.12. The ball falls into a pink paper basket.13. The basket pulls a string to turn the page of the book! • The Lever • A lever is a board or bar that rests on a turning point called the fulcrum. • An object that a lever moves is called the load. • The closer the load is to the fulcrum, the easier it is to move. • The claw end of a hammer that you use to pry nails loose is an example of a lever. • Inclined Plane • It is a flat surface that is raised on one end. • A common inclined plane is a ramp. • Inclined planes make it easier work to move objects either higher or lower. • Wheel and Axle • The axle is a rod that goes through the wheel. • The wheel, the round part, spins and turns the axle and allows both to move • It is much easier to move things with wheels and axles. • Screw • An inclined plane wrapped around a cylinder becomes a screw. • A screw has sharp ridges and is not smooth like a nail. • Screws can be used to lower and raise things. • Screws can be used to hold objects together, like the screw on lid of a jar of peanut butter! • Wedge • A wedge is made up of two inclined planes. • These two flat planes meet and form a sharp edge that can be used to push things apart. • A fork or the blade of an axe are both wedges. The edges of the blades are smooth slanted surfaces. • Pulley • Instead of an axle, a wheel can rotate a rope or cord. In a pulley, a cord wraps around a wheel • When you pull on one side of the cord, the wheel turns and the load will move. • Pulleys are good for making moving heavy loads a lot easier. • Want to see the simple machines that you use in your daily life? • Click here to find a whole house full of simple machines. Your goal is to work in groups to create a complex machine that uses at least 4 separate steps to complete the task: pop a balloon. Today, you are to draw your ideas for your machine. In the next lab, we will begin construction and testing of your complex machines. • Your goal is to work in groups to create a complex machine that uses at least 4 separate steps to complete the task: pop a balloon. • Today, you are to draw your ideas for your machine in your science notebook. • Indicate and label the steps involved as well as the simple machines used. • In the next lab, we will begin construction and testing of your complex machines. • Mousetrap image: http://www.flickr.com/photos/publik15/3847087508/ • Picture example: http://mousetrapcontraptions.com/cool-machines-3.html • Simple machines info and images http://www.fi.edu/qa97/spotlight3/inline/simplemachines.gif • http://www.edheads.org/activities/simple-machines/frame_loader.htm
